Price Beat is a ****

Price beat is a ****, bought SodaStream gas refill at R249 and Found it at Pick n Pay for R165 went to Game, the refused to refund me. and they told me about retail codes that pick n Pay uses like daah , how am I supposed to know that. Showed them the bought slips and they informed I am to bring. the item in, now all of a sudden, the picture doesn't apply.!!!!
